This Article seeks to fill a gap in legal history. The traditional narrative of the history of the American racial regulation of marriage typically focuses on state laws as the only sources of marriage inequality. Overlooked in the narrative are the ways in which federal laws also restricted racially mixed marriages in the decades before 1967 (when the Supreme Court invalidated antimiscegenation laws in Loving v. Virginia). Specifically, during the American occupation of Japan after World War II, a combination of immigration, citizenship, and military laws and regulations led to restrictions on marriages along racial lines. These laws also converged to prevent married couples, many of whom were White American soldiers and local Japanese women, from living in the United States together. Accordingly, this Article claims that the confluence of immigration, citizenship, and military laws functioned as a collective counterpart to state antimiscegenation laws.
